Long-term morphological model of Poole Harbour
No full textThe study focuses on the impact of human interventions on the natural behaviour of estuaries in response to sea-level rise. In particular it focuses on the affect of managed realignment on the critical sea level rise (SLRcrit) for the Poole Harbour. Numerical model ASMITA (Aggregated Scale Morphological Interaction between a Tidal inlet and the Adjacent coast, Stive and Wang, 1996) is used to study the response of the system to the external forcing (both natural and anthropogenic). ASMITA model schematises the tidal-inlet system and characterises each model element by a single variable volume. Volumetric data of the Poole harbour inlet elements obtained through the digitisation of the historical admiralty charts was used to calibrate the model. The model assumes that the each inlet elements tends towards an equilibrium volume which can be defined using the empirical equations. These equilibrium equations consist of equilibrium parameters that depend on the regional properties like hydrodynamics and topography of the Poole harbour. Once the model is calibrated, simulations were performed with various sea level rise scenarios (historic and future SLR) to observe the natural behaviour of the Poole harbour. Managed realignment is being introduced in the model and a range of values of critical sea-level rise was obtained and compared with the predicted sea-level rise rate given in the literature for the next century. Results suggest that the “hold the line” management scenario (current situation) would not result in the complete loss of inter-tidal flats and the coastal flooding is unlikely to occur over the next century, as a result of critical sea-level rise values exceeds the predicted rate. However research suggests, introducing realignment (coastline retreat management scenario) reduces SLRcrit values for the estuary; thus making the estuary more sensitive to the predicted future SLR rates.CoMEMHydraulic EngineeringCivil Engineering and Geoscience

Extended follow-up of a cohort of British chemical workers exposed to formaldehyde
No full textBackground: Formaldehyde is mutagenic and, when inhaled at high concentrations, carcinogenic in rats. Some epidemiologic studies have linked occupational exposure to formaldehyde with cancers of the nose, nasopharynx, and lung, but the evidence for human carcinogenicity has been inconsistent and requires clarification.Methods: We extended by 11 years the follow-up of an existing cohort of 14 014 men employed after 1937 at six British factories where formaldehyde was produced or used. Subjects had been identified from employment records, and their jobs had been classified for potential exposure to formaldehyde. Standardized mortality ratios (SMRs) were derived using the person-years method and were compared with the expected numbers of deaths for the national population.Results: During follow-up through December 31, 2000, 5185 deaths were recorded, including two from sino-nasal cancer (2.3 expected) and one from nasopharyngeal cancer (2.0 expected). Relative to the national population, mortality from lung cancer was increased among those who worked with formaldehyde, particularly in men in the highest of four estimated exposure categories (>2 ppm) (SMR = 1.58, 95% confidence interval = 1.40 to 1.78), and the increase persisted after adjustment for local geographic variations in mortality (SMR = 1.28, 95% confidence interval = 1.13 to 1.44). However, there was a statistically nonsignificant decrease in the risk of death from lung cancer with duration of high exposure (Ptrend = .18), and this risk showed no trend with time since first high exposure (Ptrend = .99).Conclusions: The evidence for human carcinogenicity of formaldehyde remains unconvincing. Although a small effect on sino-nasal or nasopharyngeal cancer cannot be ruled out, a possible increase in the risk of lung cancer is a greater concern
Cardio-respiratory morbidity and long-term exposure to particulate air pollution
No full textTo explore the long-term influence of particulate air pollution on cardio-respiratory morbidity in the UK, a cross-sectional postal survey was conducted. Women were randomly selected from the electoral rolls of 11 wards in which Black Smoke measurements had been collected over at least 30 years. Our analyses included 1,166 women aged 45 years or older who had lived within 5 miles of their current address for at least 30 years. After adjustment for potential confounders there was no clear increase in prevalence of productive cough or medically diagnosed ischaemic heart disease with long-term residence in places with higher levels of particulate pollution. The prevalence of asthma was lower in wards with the highest Black Smoke measurements (prevalence ratio 0.7, 95% CI 0.5?-?1.0). Our findings provide no indication that prolonged residence in places with relatively high levels of particulate pollution causes an important increase in cardio-respiratory morbidity. This is in contrast to observations in US studies. In view of this discordance, there is a need for further evaluation of the long-term impact of particulate pollution on health in the UK

Dinosaurs, ASD, and Social Skills
No full textA collaboration between CNN Hero Dr. Wendy Ross’ Autism Inclusion Resources (AIR) and the Academy of Natural Sciences yielded an innovation social skills group for Foundations’ Lifeworks students, matching expert museum education staff such as paleontologist Jason Poole and staff at the Academy with Drs. Mitchell and Moog. The results were nothing short of inspirational. This workshop will highlight the outcomes of the group, and share poignant stories experienced along the way. Development of self-advocacy skills and future transitions will be showcased
